This is a really, really slick looking tool. Few thoughts:
- the process of uploading a data set and creating a graph from it is very simple, but it took me a bit to find the upload button. I think it should be labeled with "Upload".
- I couldn't figure out how to change the font of the axis labels
- I don't think the user should be able to zoom out beyond the visible graph. I did this a few times inadvertently on my macbook's trackpad
- I played around with "Range Type" and lost the graph, and switching back to the original setting didn't restore it
- Descriptive statistics tool is cool. I wonder if it wouldn't be more useful to somehow display this automatically when I mouse over the column of an independent variable.
- One thing that I think makes tools like this super useful is that they're persistent and easily linkable (eg. I do some transformation to the data, graph it, and without having to press anything, I can share the link in my URL bar with someone else for them to see the same thing).
Nice work! I'll be following the progress of this.
